甘肃省农村地区不同民族糖尿病患病现状调查

The prevalence of diabetes mellitus among rural residents with different ethnicity in Gansu Province

目的分析甘肃省农村地区不同民族糖尿病和糖调节受损现状及流行病学特征。方法采用整群分层随机的抽样调查方法,对甘肃省14市州年龄20~74岁的农村常驻人群(居住≥5年)14 480人进行统一的问卷调查、物理测量和血脂、OGTT等实验室检测。结果甘肃农村地区成人糖尿病患病率为9.52%,男性10.80%,女性8.50%。男性、高龄、高BMI、经济水平较好、文化程度较低、高血压、高血脂、有吸烟史及糖尿病家族史人群是糖尿病危险因素。甘肃省农村地区成人糖调节受损患病率为16.32%,男性16.60%,女性16.10%。低教育水平、高龄、BMI、高血压、低经济水平、低海拔是糖调节受损的危险因素。糖尿病和糖调节受损随年龄增长呈线性增高。大部分少数民族的患病率低于汉族(除东乡族为12.50%,高于汉族),其中藏族(4.10%)和裕固族(5.50%)最低。藏族和裕固族糖调节受损患病率高于汉族,分别为24.70%、23.00%。结论甘肃省农村地区成人糖尿病患病率将呈增长趋势,应积极防控。

Objective To understand the prevalences of diabetic mellitus（DM）and impaired glucose regulation（IGR）among different ethnic groups in rural areas of Gansu. Methods A questionnaire survey was conducted among total 14 480 rural residents aged 20-74 years living at least 5 years in the area selected randomly from 14 towns by stratified cluster sampling method.Physical examinations and laboratory tests were also performed. Results The overall prevalence of DM was 9.52%（10.80% for man and 8.50% for women）.Logistic regression analysis showed that the risk factors of DM were men,older age,high BMI,decent family income,low education,high blood pressure,hyperlipidemia,smoking and family history of DM.The prevalence of IGR was 16.32%（16.60%for man and 16.10%for women）.Low education,older age,BMI,hypertension,low family income and lower altitude were the risk factors of IGR.Linear increases of the prevalence of both DM and IGR were noticed along with age.Compared with Han residents,the prevalence of DM was lower among major minority ethnic groups,except for those in Dongxiang.The lowest prevalence of DM was among Tibetan（4.10%）and residents with Yugu ethinicity（5.50%）,but they had higher prevalence of IGR than Han residents. Conclusions The prevalence of DM among adult residents in rural areas of Gansu is still high and will be higher in the future.
